Re: Blackberry 7.1 - VoIP audio streaming using PCMU/PCMA codecs

The below statement is correct for GSM devices. On GSM devices the default chunk size is 1024 for PCM and non PCM formats and the smallest chunk size in terms of data is 160 bytes and in terms of time is 100 milliseconds.

"If these parameters are not specified or are not valid values they will be ignored, and the recording update method will remain set to the default: data will be written every 1024 bytes."

2048 (2KB) is the smallest chunk of PCM data that you can get for multimedia audio recording using PCM format on CDMA devices.
